Clean and inspect interior (water side) of heat exchangers, remove debris and sediment build up and report any deficiencies prior to reassembly. B. Inspect all gasket surfaces, flanges, and covers for pitting, warping, or corrosion. C. Report any damage or irregularities to the Owner’s Representative prior to reassembly. 2.4 Gasket Replacement A. Furnish and install new high-temperature, manufacturer-approved gaskets compatible with steam service pressure and temperature ratings. B. Furnish and install two new manufacturer-approved boiler sections . C. Ensure all mating surfaces are clean and properly prepared before installation. D. Replace bolts, nuts, and washers required to bolt sections back together. E. Apply appropriate anti-seize compound or gasket dressing if specified by manufacturer. 2.5 Reassembly and Tightening A. Reinstall all covers, manways, and access points with new gaskets and tow new boiler sections. B. Tighten bolts in a proper crisscross pattern to recommended torque specifications. 2.6 Testing and Commissioning A. Conduct a hydrostatic and/or steam pressure test (as required) to verify all joints are leak-free. B. Restore boiler to normal operation and observe during startup for leaks or abnormal conditions. C. Provide written documentation of testing results. 2.7 Hourly Rate Requirement All bids must include an hourly labor rate for any unexpected repairs or additional services related to the boiler that are not covered under the base scope of work.
